When it comes to how Stormz brings up Mugms request to him about picking up the gold gem, you have to understand that it’s more metaphorical than actually 100%. Stormz bringing up Mugms request towards him is more of a stepping stone and a way to convey his growth and actual clearance on his goals, it is not something he is actively gunning for nor is it an actual concrete goal on achieving that.
This request is how Stormz grounds himself on the account of his instability. In the Golden Harvest book that Mugm shows Stormz, his unstable traits are commentated on. The actual goal entrusted upon him to destroy the server matters less than the fact that it was entrusted upon him despite the fact that Mugm knew Stormz very well at that point, and knew how impulsive he was.
Stormz understands his instability very well, and he understands that that is why so many of relations had burned off. He uses this to ground himself so he can be deserving of the trust he is given, so that people can trust him and not have it flipped on their head. He cares about other peoples’ assessment of him, he has brought it up multiple times (both kantje in the past, mugm now) and he wants to work on that point.
Stormz understands the fear that Dumb has of his impulsiveness, and he doesn’t take it badly, because at this point Stormz knows. He highlights upon that fact multiple times.
The gold gem request is used to work on that instability/impulsiveness of his, when dumb asks him what he will do if he gets it, that isn’t Dumb talking about that specific future, it’s them explaining to Stormz that they need him to pick a goal and stick with it, not switch at the last minute. This request is conveyed by using the Mugm request as a stepping stool.
This is also connected to the fact that Stormz has started to accurately and healthily process his past, in this case especially Total Eclipse. Stormz is able to acknowledge his wrongs and mistakes, he is able to accept the affect that it had on him and not view it in a light that is extreme. (Ie; it was completely good, it was completely bad.)
Stormz is using this moment as a focal point to establish a stable sense of identity and build that from the ground up, because he’s not going to be able to do it all by himself. The same way Dumb helped Stormz let go of the past (the stabshot) Stormz is using the request to start off with a clear cut goal that he won’t switch up on, and so he can hold onto that and allow himself to basically practice on a dream that isn’t set in stone or even realistic at all.
This is why he compares Dumb and himself to Entropy - because out of all the relationships he was clued in on or knew, entropy was one of the healthiest and using that to build himself and his relation with Dumb up is what's leading to the development happening in a positive light
